Beit-known that I, ISAGB. JONES, of Xenia, in the county of Greene, nml Stute of'Ohio, have invented new and useful Iniprovements in Wood-Sewing Machines;" and'I do hereby declarethat the following is a i full, clear, und exact description thereof, 'which willienahle others skilled inthe crt` to makepd use the same, Y i reference being had to the nccompanying'drwings, forming part of this specification. A i -The present invention relatosto certain new ond useful improvements in machines for sowing wood, whereby great strength, firmness, simplicity, und efficiency of operation aresecured, as will he obvious from thefollowing detail description thereof, reference being had to the accompanying plates of drawings, in whichi Figure 1, plate l, is a. side elevation of the machine.

Figure 2, plete 2, 'nn elevation of the machine at its front end. Figure 3, plate Zepertial plan or top View; and n y Y g Figure 4, plate 2, a detail lview oi the dog and its lever and spring for holding the log while being served. Similar letters lo i reference indicate like parts. I I I' A, in the drawings, represents th'ie'i'ramework of the machine, which may he mudo of any suitable construc-A tion to receive the various working parte constituting the same. B, the drivii1gshuft, turning in heariogsat oneend of the framework A, und extending across the same. On cach end of the 'shaft Bris-e crankhondle, `Chieri i convenience in turning it, and between the two sides of the fremeworkit has a.' gearivheel,"D,isccurcdto it th meshes into the pinion-wheel E of the transverse horizontal shaft F, turning-in hearings'oi'thefiiievrklfi below the shaft B. On one end of tho-shaft F is u balance or flywheel G.' H, o connooting rod,'hung by one,` end to flywheel, and at its other to thelowcr end of o. pendulum-armyl, that is fixed to one end of a transverse rocker-shaft or beam, J, arranged to turn iny bearings et therein' end of' the framework A.y VThis connecting- .rod H passes at k-ot the frnmework through u verticail' guide-Piece, there placed, to keep it frourspriiigng when running. l To the pendulum-arm I, olioverefcr-red to, iselso hung a rod o rurgmM, that, pessingtoward i n the front end of the machine, through ovcrtical guide-piede, N, upon its sidefrninework,l1 as therc'attacheii to it and carries a.` strained sowbaclr fraaie, 0. This Vsmv-frame, by its'hack piece P,' pluys through sloop, Q, zii-ranged to slide up and down upon n vertical V'guide-post, R,`\ri th the cutting-edge of thesw'fdoln. end in position to act upon a. log, when. placed upon the rests S therefor, at the frontend of' ythe muchne; und there secured und h'eld, as will behereinfitcr descrihed..v 'I I Q f Upon the opposite siilc'ot' thgingchine to that" carrying the sow und connecting partsnbov'efdoscrihe,

another saw-blade, T, is srrugeilngo iuovc, in n similar manner, through ai connecting-rod, pcndulumlar'm and' rod, vertical guides, und slide-loop, Z, of post A", thc only diii'e'rence being thot 'the conncutionirth the sllorft is through o crnnk-urm, A, in lieu oi' o. wheel, ns was described in Vthe iirstiinstence.`

For holding thc log in position while being served, the following arrangement of parte` is providedr, u lever-handle or arm projecting from front end of machine, and extending back to its roer end, or nearly so, where it is hung on-a. fulcrum or centre-pin.4 f El, n bent spring on under side of lever-arm C, along which it extends in position to bear-upon the log placed upon the rests therefor, hcreinbcfore referred to'.- Tix-elevar C carries a dog, F, thon-when the lever is depressed, grasp's the'log, und, ill-connection withthe spring Eholds it, by catching the lever into the propcr'notch or' tooth Gi ofv the ratchet-bor H2 fixed to the front end of tho;A machine ina. vertical position. 4 v i vThe machine above described, and equipped with two strained saw-backs, isudnpted more purticulrl] for cutting a log into three pieces at the some time, but in sawing lnr'ge logs, shingle-timber, 20., the two n*- frames are reinoved, and, for one of them, o straight saw-blade substituted, and the mochine set up to the log.

` By the hanging the saw-blades to a working-shaft through pendulum-arms, as above describedtheruhbing und friction of lparte is greatly obviateii, and u rocking motion imparted to the saw.

What I claim as new, and desire to secure by Letters Potent, isi `The combination of the lever C, dog Fspring Ez, and ratchet-bar H, all constructed so described for the purpose specified. U 1- Witnesses:
